UPDATE access to the System level symbolic resources are limited to System Programmers, DASD Administrators, and/or Tape Library personnel. All access is logged. Ensure the guidelines for the resources and/or generic equivalent are followed. Limit access to the IEASYMUP resources to above personnel with UPDATE and/or greater access. The following commands are provided as a sample for implementing resource controls: rdef facility ieasymup.* uacc(none) owner(admin) - audit(all(read)) - data('protected per acp00350') rdef facility ieasymup.symbolname uacc(none) owner(admin) - audit(all(read)) - data('protected per acp00350') pe ieasymup.symbolname cl(facility) id( |
